Patent

CA 2260127

The invention relates to a running gear (3) for a guide rail (1, 1') with a dividing wall or similar suspended on the running gear. Said running gear has a support roller (9) and two guide rollers (12). According to the invention, the guide rollers (12) have a vertical section in the shape of a truncated cone, and are brought up with their exterior surface (14') as far as the exterior surface (15) of the support roller (9), allowing a slight clearance (S3). Said guide rollers (12) are positioned in guide roller accommodating elements in such a way that the clearance (S2) between the rail section running above the supporting roller and the guide rollers, and the supporting rollers or guide rollers is approximately equal.

L'invention concerne un mécanisme de roulement (3) pour un rail de guidage (1, 1') avec une cloison ou un autre élément comparable suspendu au mécanisme de roulement, le mécanisme de roulement comportant un rouleau porteur (9) et deux rouleaux de guidage (12). Selon l'invention, les rouleaux de guidage (12) présentent une section verticale tronconique et sont approchés de façon que leur surface d'enveloppe (14') aille jusqu'à la surface d'enveloppe (15) du rouleau porteur (9) tout en conservant un faible jeu (S3). Ces rouleaux de guidage (12) sont en outre logés dans des logements de réception de façon telle que le jeu (S2) entre le rail profilé passant au-dessus du rouleau porteur et des rouleaux de guidage, d'une part, et le rouleau porteur ou les rouleaux de guidage, d'autre part, est à peu près identique.
